... Polarization: the redistribution of charge within a group of particles that produces an apparent charge on the surface of an object. When Polarized- net charge = 0 * No charge has actually been transferred. * Charge is only REDISTRIBUTED. Ex: A polar molecule- one side of the molecule is more positi ...

... by inspection. Second, because P is on the line bisecting the 2 positive charges (located at (a, 0) and (0, -a)), the portions of the field perpendicular to that bisecting line will cancel, leaving a field pointing along that line, or at 45° above the –x-axis. Alternative approach –The direction is ...
